a) The vast temple interior created by Chris Foss had the look of something that was created for giants. The explorer lowers himself from the shaft above above a plinth that might be as large as a three or four story building and perhaps it looks as if it could easily be an oven with a kitchen chimney above it.

b) Vast shaft entrances on the side of the plinth might be the air intakes of huge long engines for airborne craft , the left might secretly be a representation of a strange creature with wide open maws and eyes on top of stalks that seem like siamese twin versions of military ships radar antennae. and long fins or wings sticking out of the back.
